FLEXIBLE EARROW.

.pplcation filed May 3,

The prescnt invention relates to a liarron ol" tl1c surface type, and iias for its pr1nc1pal object to provide an implement of this nature which may be attachod begrain drill, roller, or the -like in order to perform disi i 5; and harrowing in one operation, withot the nced ol added l1orse power.

Anothcr important object of the invention is to provide a flexible surface harrow of tlxis nature which is eflicient and reliable in operation npon the soil for prodncing a srnooth and mcllow seed bcd.

A still further Very important object of the invention. resides in the provision 01" a harrow oi this nature which is xceediiigly simple and 'light in its construction inexpensive to manufacture, adjnstable to afford difi'erent angnlar engagements 01" tlie tines with the gronnd, is strong, durable, easy to nianipnlate, not likely to easily become out of order, and othorwise well adapted to the pnrpose for which it is designed.

With the above and nnmerons other objects in VieW as will appear as the description proceeds, the invention resides in certain novel ieatnrcs of construction, and in the combination and arrangement of parts as Wlll be hcreinafter more fully described and claimed.

In tlre draxving:

Figure 1 is a top plan view of the harrow cmbodying tire eaturcs of my invention,

l 3 a detail view or the cross beam.

Relerring to the draWing in detail, it will be seen that the latter T denotes a tongne inclnding a front section 5 and a rear section 6, these sections being hinged together at 7. On the front end of tlre forward section 5, there is monnted a cleVis 8 in order tnat attaclnnent 1nay lie mounted tor draft pnrposes with a cnltivator or the like.

A cross beam is indicated generally by the letter B and inclndes npper and loWcr rods 9 for recciViilg between their intermodiate portions, tlio rcar end of the sections 6 engaged therewith by pin 10 or in any other preferred manner. The extremities 0.1 the rods 9 are fixed together by elements 11 which also hold in place brackcts l2. Brace ar1ns 13 are, attached as at 14tto the torward end of the rear section 6, and between the extremities of the rods 9 at 15, the rear extremities of these brace rods 13 terminating in'hooks 16.

A crossplate 18 is ztizzed to the section 6 in advance of the beam B, and has its extremitles provided with apertures 19 receiving the hook ends 20 of links 22, the rear ends of which terminate in eyes 23. A pair of harr ow implements is indicated by the letters l-l. Each implement includes a head 25 lravingu plnrality of straight tines or teeth projecting theretroni. An eye 27 is 1nonntcd on the intermediate portion 01 cash head and engages one of the hooks 16. An c}re is 1nounted at the inner end of each head 25 and engages tlie eye 23. Cranks 29 are rigidly attached to the heads 25 to normally project upwardly and rearwardly tlierel" The lower ends of these cranks are bi;tnrcated to forrn slots 30 across which entends pins 31. A pair of arcuate members 32, each have one of their ends pivoted at to one of the bracltets 12. The 1neinbers 32 entend throngh the slots 30 and have notoires or teeth 34tengageable with pins 31.

lt Wlll thus be seen that loy placing the pins 31 in the notches 34, that the angles et the harrow implements 8 may be changed in relation to the frame Which is made up of the section 6, the braces 13, and the beam B.

Particular attention is directed to the ease Wi tl1 which the harrow implements may be attached to or detachcd from the trame. lie structure is capable of being manniactured very cheaply and liqhtly Withont sacrificing its strength and dnrability. The structure will operate very efliciently to attain tire ends desirech andthe harrow iniplements may be readily adjnsted as is desirablc. The many desirable advantages and features of the present structure Wlll be apprcciated by those amiliar with the class of agricultural machines to which the present application appertains, and the cooperation and coaction of the various parts is to be noted. The trame holds tl1e harrow implcments in order that they may reely flex with relation thereto so that tlie maxi- HiilHl efliciency is attained.

Tl1e contrivance is designed as an ancillary tool or implement to be used in connection with and attached to the disk, grain drill, or relier, whereby the seed bcd may be prepared and completed in one operation. The present invention is in the form of an attachment, which afiords ease of assemblv. The invention is adapted for use only with other implements and the structureafords details of construction, and in the combinatien and arrangement of parts may be re-' sorted t0 withont departing from the spirit or scope of the invention as hereinafter laimed, or sacrifieing any of its advantages.

Having thns described my invention, what I daim as new is:

1. An attaclnnent of the class described inclnding, in combination, a tongue formed in a pair of hinged sections, a cross beam comprising a pair of rods having their in tern1ediate portions spaced to receive 0ne end of the tangue therebetween, means fixing the tongne to the cross beam, brackets affixed to the cross beam, brace arms engaging the tongue and the ends of the cross beam and terminating in hooks to the rear of the cross beam, a pair of harrow implements each comprising a head and a plnrality, 01 teeth, an eye boit on the center of the head engaged with one of the hooks, an eye boit at one end of the head and a hook on the last mentioned eye boit, a plate fiXed to the tongue forwardly of the cross beam and having apertured ends for receiving the last mentionod hooks, a pair of arcnate members having a plurality of notches and havinp their ends pivotally engaged on the brackets, cranks rigidly extending from the heads of the harrow implements, and pins on the cranks for engaging the pivoted arcuate me1nbe1s.

2. An attachment of the class described inciuding a trame having a pair of hooks extending rearwardly thereof, a plate on the frame having apertnred ends, and a pair of harrow i1np]ements, each comprising a head. a giurality 01? teeth, an eye boit on the center of the head engaged with one et tire hooks, an eye boit at one end of the head, a hook on the last mentioned eye boit engage ab1e with one and of the apertured plate, brackets on the frame, arcuate notch mem bers pivotod to the braekets, cranks on the heads of the harrow implements, pins on tire cranks, engageable by the areuate ment bers.

in testimony whereof I afiix my signature.
